We look at the division of 71915353 by 850 
We want to figure out the number of times 71915353 can be divided by 850.

Moving on to step 1:
When dividing 7 by 850, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 850

Moving on to step 2:
The number 850 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 850

Let's proceed to step 3:
The number 850 fits into 719 0 times, leaving a remainder of 719.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 719 after subtracting 0 from 719.
Grab the next digit (1) from the dividend, add it to 719, then carry on: 7191 / 850

On to step 4:
When dividing 7191 by 850, we get 8 with a remainder of 391.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6800 from 7191, we get 391.
Bring next digit (5) of the dividend behind the 391 and repeat the process: 3915 / 850

Step 5:
850 can be fit into 3915 4 times, resulting in a remainder of 515.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtract 3400 from 3915 to get 515.
Bring next digit (3) of the dividend behind the 515 and repeat the process: 5153 / 850

On to step 6:
850 goes into 5153 6 times with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.0
If we take 5100 away from 5153, we end up with 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 850

Let's proceed to step 7:
535 divided by 850 is 0 with a remainder of 535.
Use 0 as the next digit of our solution. 
Result so far: 8460.0
Subtracting 0 from 535 leaves us with 535.
Grab the next digit (3) from the dividend, add it to 535, then carry on: 5353 / 850

On to step 8:
5353 divided by 850 is 6 with a remainder of 253.
The next digit of our result is 6. 
Result so far: 84606.0
Deduct 5100 from 5353 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
If we divide 2530 by 850, we get 2 and a remainder of 830.
Write down 2 as next digit of the result. 
Result so far: 84606.2
The remainder is 830 after subtracting 1700 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 10:
If we divide 8300 by 850, we get 9 and a remainder of 650.
Write down 9 as next digit of the result. 
Result so far: 84606.29
Subtracting 7650 from 8300 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 11:
If we divide 6500 by 850, we get 7 and a remainder of 550.
Record the quotient 7 as the next digit in the result. 
Result so far: 84606.297
Subtract 5950 from 6500 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 12:
850 can be fit into 5500 6 times, resulting in a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 84606.2976
If we subtract 5100 from 5500, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
If we divide 4000 by 850, we get 4 and a remainder of 600.
Write down 4 as next digit of the result. 
Result so far: 84606.29764
If we subtract 3400 from 4000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 14:
The number 850 fits into 6000 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 84606.297647
If we take 5950 away from 6000, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
850 goes into 500 0 times with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 84606.297647
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 16:
The number 850 fits into 5000 5 times, leaving a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 84606.29764705
If we subtract 4250 from 5000, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

The quotient of the division is 84606.29764705, and the remainder is 7.5e-07.
